remove non-draft-state features from quizzes

fixes CNVS-16048

test plan:
  - do regression testing around publishing / unpublishing quizzes
    - all publishing / unpublishing scenarios should work correctly
    - make sure to check publishing on:
      - quizzes#index
      - quizzes#show
      - from modules
      - from module items
    - make sure that warnings about unpublished quizzes work
    - make sure that warnings about not being able to unpublish quizzes with
      submissions work
    - make sure that the module sequence footer still works on the quizzes page
    - make sure we can still review published quizzes in speedgrader
